Comments on the article

To give locksmith products beautiful view, resort to various means depending on the nature of the work. Small artistic forgings acquire a beautiful appearance if, at the end, they are supplied with an intense black color. But for such works, the paint is not applied by spreading, but the following operations are performed: a fire is lit in the furnace, corresponding in size to the size of the object being processed.

The fire should not smoke (it is best to use coke for this). Then they lubricate the object with ordinary linseed oil and expose it to the action of fire, but only for such a time until the oil evaporates and its residue burns to the iron. After cooling, rub the object firmly with a cloth lightly soaked in linseed oil.

The smoother the surface of the iron received during processing, the more beautiful the deep black color will look. This coloring is extremely strong and perfectly protects from atmospheric influences.

In order to pickle iron parts black, they must be clean, brilliantly straightened and polished. Then they are lubricated with liquid oil and sprinkled with wood ash, then they are held over hot coals until a run-down black color is obtained. After cooling, the objects are washed in water to which a few drops of sulfuric acid are added, and immediately wiped thoroughly with a coarse, clean cloth.

Rubbing with oil protects the product from exposure to air. To make iron especially soft, it is heated red-hot, quickly cooled in soap, heated again to red heat, and put into powdered lime, allowed to cool slowly. When processed in this way, iron becomes very malleable and soft.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

AudioQuest NightHawk headphones with natural biocellulose cones 18.09.2015

AudioQuest introduced the NightHawk headphones, which, according to the manufacturer, are changing the established ideas about these products. The creators of AudioQuest NightHawk tried to combine high sound quality, comfortable shape and attractive appearance in headphones.

Unlike most headphones that use Mylar cones (a film of polyethylene terephthalate fibers), the AudioQuest NightHawk headphones use 50mm drivers with "natural biocellulose" cones. This material, according to the manufacturer, allows you to get a cleaner sound compared to mylar.

The diffuser's rubber surround is highly flexible and retains its shape well. The manufacturer also notes the even distribution of ventilation holes in the ear cups, which eliminates the risk of voice coil distortion and associated distortion, and improves the reproduction of low-frequency vibrations.

Headphone impedance - 25 Ohm, sensitivity - 100 dB / mW, maximum input power - 1,5 W.

NightHawk comes with two cables to connect to the source. One of them, according to the manufacturer, allows you to get the maximum sound quality, and the second is characterized by increased strength.

The AudioQuest NightHawk headphones are already on sale for $599.
